Description

TECHNICAL FIELD

The present invention relates to a serotonin reuptake inhibitor. The serotonin reuptake inhibitor of the present invention is a selective serotonin reuptake inhibitor that has affinity for serotonin 1A receptors, has a small inhibitory effect on the reuptake of dopamine and noradrenaline, and strongly inhibits serotonin reuptake. In addition, the present invention relates to novel compounds having such a selective inhibitory effect on serotonin reuptake. Furthermore, the present-invention relates to novel benzylpiperidine derivatives that are intermediates for synthesizing such compounds, and a process for the production of the derivatives.

BACKGROUND ART

Depression is a chronic disease that affects persons of all ages. Of various antidepressants used at present, the most successful antidepressants are selective serotonin reuptake inhibitors (hereinafter abbreviated as SSRI in some cases). SSRI has serotonin reuptake inhibitory effect more selective than dopamine and noradrenaline reuptake inhibitory effect. The first drug put on the market as SSRI is zimelidine. Other SSRIs that have been put on the market or are under development include, for example, fluoxetine, fluvoxamine, citalopram, cericlamine, femoxetine, ifoxetine, cyanodothiepin, sertraline, paroxetine and litoxetine.

Although SSRIs are the most successful as antidepressants at present, several problems in them are pointed out. Of these problems, the following two problems are typical: about one-third of all melancholiacs are so difficult to cure that SSRIs are not sufficiently effective, and the exhibition of a sufficient clinical effect of SSRI requires 3 to 8 weeks. In particular, this slow exhibition of antidepressant effect causes the following problems. Since SSRIs exhibit side effects immediately though they exhibit antidepressant effect slowly, there is a vulnerable period in which the patient undergoes only the side effects without obtaining the therapeutic effect of the drug. Therefore, persuading the patient into continuing the same treatment also in this period is often a heavy burden for a doctor in charge. In addition, because of the gradual beginning of experience of the effect, a patient who tends to commit suicide resumes initiative before experiencing sufficient improvement of depressive condition. Therefore, there are, for example, a risk of suicide and a necessity for frequent admission into a hospital. Accordingly, the development of an antidepressant capable of exhibiting its effect rapidly is desired.

The reason why the exhibition of the antidepressant effect of SSRI requires several weeks is as follows.

SSRI inhibits rapid serotonin reuptake in serotonin metabolic turnover. Since this action takes place at the nerve ending of each serotonergic neuron, neurotransmission due to serotonin is enhanced. The inhibition of rapid serotonin reuptake by SSRI, however, takes place also in serotonergic neuron cell bodies and dendrites, which are present in raphe nucleus. Therefore, the firing auto-inhibition (the negative feedback reaction) of the serotonergic neuron through 5-HT1A auto-receptor is also enhanced in the raphe nucleus. As a result, the neurotransmission in the serotonergic neuron is not enhanced to an expected degree as a whole by initial administration of SSRI. On the other hand, in the course of continuous taking of SSRI for several weeks, serotonin 1A auto-receptors present on serotonergic neuronal cell bodies and dendrites in the raphe nucleus are desensitized, so that the negative feed back reaction is abolished. As a result, the firing inhibition of the serotonergic neuron is broken down, so that the enhancement of the activity of the serotonergic neuron and the inhibition of serotonin uptake at the nerve ending succeed cooperatively. Therefore, the serotonin neurotransmission is enhanced, resulting in exhibition of the antidepressant effect.

Accordingly, the reduction of a period required for the exhibition of the effect of SSRI or the enhancement of the antidepressant effect may be achieved either by stopping the negative feedback reaction of serotonin by inhibiting the serotonin 1A auto-receptor by the use of a serotonin 1A receptor antagonist, or by reducing a period required for the desensitization by positively stimulating the serotonin 1A auto-receptor by the use of a serotonin 1A receptor agonist. That is, a compound having affinity for serotonin 1A receptors and a selective inhibitory effect on serotonin reuptake has a marked antidepressant effect and hence may be used as a therapeutic agent for psychiatric diseases which exhibits its effect after a reduced period. In fact, it has been reported that, for example, pindolol having a high affinity for serotonin 1A receptors increases the effect of a serotonin reuptake inhibitor in a melancholiac and reduces a period required for the onset of the effect (Arch, Gen. Psychiatry, (1994), 51, 248-251).

There are many references concerning derivatives containing two nitrogen-containing saturated heterocyclic rings represented by a piperidine ring in the molecule. Among these derivatives, as bispiperidine derivatives having two piperidine rings bonded to each other through an alkylene chain at the 4-potision and 1-position, there have been disclosed, for example, benzoylpiperidine derivatives as therapeutic agents for Parkinson's disease in GB1250719. In addition, EP512901 discloses 1-aralkyl-4-aryl-4-piperidinoalkylpiperidine derivatives as substance P antagonists and neurokinin. WO97/09308 discloses indole derivatives as neuropeptide Y antagonists. WO98/27085 discloses cyclic carboxyamide derivatives as tachykinin receptors antagonists. WO2000/023438 discloses imidazolylalkyl-piperidine derivatives as H3 agonists. WO2000/035877 discloses heterocyclic piperidine derivatives as chemokine receptor regulators. Further, DE19908483 discloses pyridine derivatives as inhibitors of nicotinamide mononucleotide production. None of these prior art references, however, report that the compounds disclosed therein have inhibitory effect on serotonin reuptake. In addition, JP-A-2001-131149 discloses bispiperidine derivatives having inhibitory effect on serotonin reuptake, but it reports that these derivatives should have two other ring structures besides piperidine rings.

As to cycloalkyl derivatives having a 4-benzylpiperidinoalkyl group as a substituent, FR7031, for example, discloses phenylcyclohexane derivatives having anticonvulsant and analgesic effects. In addition, DE3614907 discloses N-substituted piperidine derivatives as fungicides. WO9418172 discloses imidazolylbenzene derivatives as NMDA antagonists. WO00/35449 and WO00/35452 disclose piperidine derivatives as chemokine receptor regulators. None of these prior art references, however, report that the compounds disclosed therein have inhibitory effect on serotonin reuptake.

Furthermore, as to non-aromatic heterocyclic derivatives having a 4-benzylpiperidinoalkyl group as a substituent on the carbon atom of the derivative, DE19531321, for example, discloses N-phenyl-oxazolidinone derivatives having effects on central nervous system. In addition, DE4037426 discloses benzoxazione derivatives as anti-inflammatories. None of these prior art references, however, report that the compounds disclosed therein have inhibitory effect on serotonin reuptake.

Test Example 1

Screening Test Using [³H]Paroxetine Binding

1-1. Preparation of a Cerebral Cortex Membrane Preparation

The membrane preparation was prepared according to the method^1a) of D'amato et al. In detail, after a male rat was decapitated, the whole brain was immediately removed and the cerebral cortex was dissected therefrom under ice-cooling. A buffer solution (50 mM Tris-HCl (pH=7.4), 120 mM NaCl, 5 mM KCl) was added to the cerebral cortex in an amount of 25 times the wet weight of the cerebral cortex, followed by homogenization in an ice bath by the use of a Teflon-glass homogenizer. The homogenate was centrifuged at 4° C. and 45,000×g for 10 minutes, and the resulting precipitate was dispersed in an ice-cooled buffer solution (50 mM Tris-HCl (pH=7.4), 120 mM NaCl, 5 mM KCl) by the use of Hiscotron™, followed by centrifugation at 4° C. and 45,000×g for 10 minutes. The resulting precipitate was re-suspended and the washing procedure was repeated. The membrane preparation thus obtained was suspended in the same buffer solution as described above, and then subjected to cryopreservation at −80° C.

1-2. Receptor Binding Experiment

[³H]paroxetine binding was measured according to the method^1b) of Habert E et al. In detail, 200 μl of a dilution (final concentration: 0.15 nM) of [³H]paroxetine with 50 mM Tris-HCl (pH=7.4) buffer containing 120 mM NaCl and 5 mM KCl, 790 μl of the cerebral cortex membrane preparation (150 μg/tube in terms of protein), 10 μl of a solution of a test drug in dimethyl sulfoxide and 1 ml of the above-mentioned buffer solution were mixed to prepare a liquid having a total volume of 2 ml. After this liquid was allowed to react at room temperature for 60 minutes, it was immediately filtered by suction at a low pressure through glass fiber filter. The glass fiber filter was washed 4 times with 4 ml of the same buffer solution as above and then transferred to a glass vial containing 4 ml of ACS-II (Amersham), and the radioactivity remaining on the filter was measured with a liquid scintillation counter.

Non-specific binding of [³H]paroxetine was defined as the amount of [³H]paroxetine bound in the presence of 100 μM 5-HT.

Rate of binding inhibition was calculated by the following equation:

Rate of binding inhibition (%)=100−100×{[amount of [³H]paroxetine bound in the presence of test substance]−[amount of [³H]paroxetine bound in the presence of 100 μM 5-HT]/[amount of [³H]paroxetine bound in the absence of test substance]−[amount of [³H]paroxetine bound in the presence of 100 μM 5-HT]}

Test Example 2

[³H]8-OH-DPAT Binding Test

2-1. Test Method

The test was carried out according to the method² of Hall M. D. et al. After about one week of pre-breeding, a male rat was decapitated and the brain was immediately removed. The hippocampus was dissected from the brain on ice, and 50 mM Tris-HCl (pH=7.4) was added to the hippocampus in an amount of 40 times the wet weight of the hippocampus, followed by homogenization (3 min, 1 stroke/min) in an ice bath by the use of a Teflon-glass homogenizer. Then, the homogenate was centrifuged (4° C.) at 40,000×g for 10 minutes. The resulting precipitate was dispersed in an ice-cooled buffer solution (50 mM Tris-HCl (pH=7.4)) by the use of Hiscotron™, followed by centrifugation (4° C.) at 40,000×g for 10 minutes. Moreover, the resulting precipitate was re-suspended and the washing procedure was repeated once. The precipitate thus obtained was dispersed in an ice-cooled buffer solution (50 mM Tris-HCl (pH=7.4)) by the use of Hiscotron™, and the resulting dispersion was incubated at 37° C. for 1 hour and then centrifuged (4° C.) at 40,000×g for 10 minutes. Furthermore, the resulting precipitate was re-suspended and the washing procedure was repeated once. The membrane preparation thus obtained was suspended in the same buffer solution as described above, and then subjected to cryopreservation at −80° C.

Measurement was carried out by using a liquid for reaction (total volume: 200 μl) obtained by adding 50 μl of [³H]8-OH-DPAT (final concentration: 2 nM), 4 μl of a solution of a test drug and 146 μl of the hippocampus membrane preparation (80 μg/tube in terms of protein) to a buffer solution containing 50 mM Tris-HCl (pH=7.4) and 4 mM CaCl₂. After the liquid for reaction was allowed to react at room temperature for 30 minutes, it was immediately filtered by suction at a low pressure through glass fiber filter. The glass fiber filter was washed twice with 250 μl of a buffer solution and then added to a glass vial containing 4 ml of ACS-II (Amersham), and the radioactivity bound to receptors and remaining on the filter was measured with a liquid scintillation counter. Non-specific binding of [³H]8-OH-DPAT was defined as the amount of [³H]8-OH-DPAT bound in the presence of 1 μM 8-OH-DPAT.

Rate of binding inhibition was calculated by the following equation:

Rate of binding inhibition (%)=100−100×{[amount of [³H]8-OH-DPAT bound in the presence of test substance]−[amount of [³H]8-OH-DPAT bound in the presence of 1 μM 8-OH-DPAT]/[amount of [³H]8-OH-DPAT bound in the absence of test substance]−[amount of [³H]8-OH-DPAT bound in the presence of 1 μM 8-OH-DPAT]}

Test Example 3

5-HT_1A Receptor Stimulation Test

3-1. Cells Used and Preparation of a Membrane Preparation

CHO cells expressing human 5-HT_1A receptor (human 5-HT_1A/CHO) were used in the experiment. The cells were cultured in F12 containing 10% FCS, 500 μg/ml Geneticin and 100 U/ml penicillin-100 μg/ml streptomycin (all available from GIBCO) in a 5% CO₂ incubator, and a membrane preparation was prepared according to the method³⁾of A. Newman et al. In detail, cells scraped and collected by the use of buffer solution A (20 mM HEPES, 5 mM MgSO₄) were homogenized in a Teflon™ homogenizer, followed by centrifugation (50,000×g, 30 min, 4° C.). The precipitate was re-suspended in a suitable volume of buffer solution A and stored at −80° C. until use. The amount of protein in the membrane preparation was determined with Dye Reagent Concentrate (BIO-RAD) by using Albumin Bovine (SIGMA) as a standard substance.

3-2. Experimental Method

Binding of [³⁵S]GTPγS to human 5-HT_1A receptors was measured by the use of the above-mentioned membrane preparation according to the method³⁾of A. Newman et al. In detail, 0.05 nM of [³⁵S]GTPγS (E.I. du Pont de Nemours & Co. NEN) and a definite amount (about 50 μg/tube) of the membrane preparation were added to buffer solution B (20 mM HEPES, 3 mM MgSO₄, 3 μM GDP, 1 mM DTT) containing 10⁻⁵ M of each test substance, and the resulting liquid for reaction having a total volume of 1 ml was incubated at 22° C. for 20 minutes. After completion of the reaction, the reaction mixture was diluted with 5 ml of ice-cooled buffer solution B, and the dilution was immediately filtered by suction through glass fiber filter (Whatman, GF/B) to terminate the reaction. The glass fiber filter was washed twice with the same buffer solution as above and placed in a vial, and 4 ml of ACS-II was added thereto. The radioactivity of [³⁵S]GTPγS on the filter was measured with a liquid scintillation counter. The amount of [³⁵S]GTPγS specifically bound was calculated from the amount of [³⁵S]GTPγS non-specifically bound in the presence of 10 μM of GTPγS (Sigma). The 5-HT_1A receptor stimulating activity of each test substance was expressed in terms of the rate of increase in [³⁵S]GTPγS binding by taking an increase in [³⁵S]GTPγS binding caused by 10 μM of 5-HT, as 100%.
